Custom cable company introduction: laying insulated cable to do several resistance telemetry

Custom cable company introduced insulated cable is we often mentioned in the construction of fire-resistant cable, and the technology has been very mature. Although insulated cables have many advantages that other ordinary cables cannot match, but because the material of the insulating layer is mostly made of magnesium oxide, it is particularly easy to be affected with moisture when in contact with the air, and the resistance is extremely sensitive during the laying process. The following is a reputable custom cable company to introduce several resistance telemetry when laying insulated cables.

The first time: the day before the formal construction, the custom cable company reminded everyone to pay attention to the telemetry of the resistance of the insulated cable to detect whether the magnesium oxide insulation layer of the cable has been damp. If the resistance value of the cable is found to be unqualified in the test, indicating that the magnesium oxide in the insulation layer has been affected with moisture, then the unqualified insulated cable will be baked until it is qualified in the test resistance, and then immediately sealed; If the test is qualified, the product terminal will be sealed immediately to prevent the magnesium oxide in the insulation layer from absorbing moisture in the air and affecting the insulation of the cable.

2nd: Before the official start of construction, the custom cable company wants to do another telemetry on the insulated cable. This is done to check whether the previous terminal seal is qualified. If the resistance of the cable is qualified in the telemetry of the previous day, but it is not qualified before the formal laying starts, it means that our sealing work on the terminal is not qualified, and the cable needs to be baked again and sealed quickly.

The third time: after the laying of the insulated cable is completed, the cable shall also be telemetered to determine whether the resistance is qualified. if the resistance of this telemetry is unqualified, it indicates that there is a mistake or improper construction method, resulting in insulation failure in the cable. Once this happens, the custom cable company hopes that the construction personnel will immediately investigate the laid cables, find the damaged and invalid places of the cables, cut the damaged parts, and then link them with the intermediate connectors to test whether they are qualified again until the whole cables are qualified.

Due to the excellent performance of insulated cables in fire prevention, waterproof, corrosion resistance, etc., and the laying process is relatively simple, many local construction companies will customize this cable through custom cable. In the process of laying, the custom cable company with good quality and good reputation hopes that the construction personnel will do a good job in each resistance telemetry.
